JOIN'L STRIP.

Original No. 1,653,012, dated December 20,

This invention relates to joint strips.

.It is of particular advantage in joints such as exist between the hood of an automobile and the supporting surfaces at the end of the hood at the back of the radiator and at thefront of the ordinary cowl, but is ob viously applicable to any oints where suchstnps are used. These surfaces or seats are usually provided with perforations through which leather lacings are arranged to silence thev relative movement of the parts. The object of the invention is to provide a con,- venient means for surfacing this and similar joints.-

The invention is illustrated in the accompanying drawings as follows ig. 1 shows a tion of a hood.

Fig. 2 a longitudinal section of a silencstrip on the line 2-2 in Fig. 3. Fig. 3 a section on the line 3.3in Fig. 2. 1 marks the hood, 2 a seat at the rearof the hood such asis ordinarily used in. auto.- mobiles, the seat being usually of sheet metal and having perforations 3. A typical hood 4 is shown resting on the seat 2. A silencing strip 5 is formed of rubber and has a series of projections 6, these projections being spaced apart to correspond with the spacing of the perforations 3 as indicated in dotted lines in Fig. 1. The projections 6 have an undercut portion 7 which when in place inthe openings 3 look the projections in the openings through the elasticity of the rubber.

In an application filed by me, Serial Number 641,374 filed May 25th, 1923, I have Shown the projections having an undercut portion as 7 in a rubber strip broadly similar to the strip herein shown. Some difliculty perspective view of a por' 1927, Serial No. 653,781, flledl'uly 25, 1823. Application for reissue filed June 21, 1928. Serial has been experienced in forcing the rubber pro ections into the openings 3 and in order to overcome this objection I provide a tapered extension 8 by means of which the projection may be readily started in the perforation 3 and thus compressed radially so that the projection can be readily pressed through the opening intoplace.

s a Wearing surface I provide ribs 9 which extend in a longitudinal direction relatively to the strip. These not only afi'ord a desirable surface for the seat of the hood but where there is an open fit of the hood these ribs make a natural finish along the edge of the hood. v

What Iclaim as new is 1. A jointst-rip of yielding and stretchable material with projections formed on one face thereof adapted to enter perforations in a jointmember to secure the strip 1n place, said projections comprising an undercut portion adapted to yieldingly enter the perforations and hold the strip in place thereon, said undercut portion having a tapered extension facilitating the entry of the projections into the perforations.

2. A joint strip of yielding and stretch-' able material'comprising a contact portion HANS G. JORGENSEN.
